UNirn STATES PATENT F F ICEo ALBERT EVERETT LOOKHART, OF EAST CAMBRIDGE, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 360,315, dated March 29, 1887.

Application filed December '20, 1886. Serial No. 122,065. (No model.) Patented in Canada December-28, 1886, No. 23,640.

To all whom it may concern.-

Be it known that I, ALBERT EVERETT LOCK- HART, of East Cambridge, in the county of Middlesex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Fastenings for the Covers of Boxes, Burial-Caskets, &c.; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a top view, Fig. 2 a side elevation, Fig. 3 a front end elevation, and Fig. 4 a longitudinal and median section, of the upper portion or member of my improved fastening. Fig. 5 is a top view, Fig. 6 aside ele vation, and Fig. 7 a longitudinal and median section, of the lower portion or member of my said fastening. Fig. 8 is a top view, and Fig. 9 a side view, of the two members in engagement with each other.

The invention herein described has been patented by me in the Dominion of Canada by Letters Patent numbered 25,610, and dated De cember 28, 1886.

In order to secure a cover to a box orburialcasket body, two at least, and generally six, of the fastenings are used, the upper member of each being secured to the cover and the lower member to the box or casket-body, in the upper edge of such body.

My said fastening is analogous to those described and shown in the United States Patents Nos. 191,995 and 288,189, though materially differing in construction from either, each member of my said fastening being composed of sheet metal struck into form by dies.

The upper member, A, circular or thereabout in shape, is bent along its middle so as to form in it a concavo-convex and tapering catch, a, on opposite sides of which are two countersunk holes, Z), for reception of screws for fastening the member to a cover.

The member B, made of sheet metal and formed by dies, has in it at its ends countersunk holes 0, for receptionof the screws for fastening it to the upper edge of a box or cats ket-body. Between the screw-holes there are a furcated opening, (I, a guidegroove,e,arranged with and leading from the base of such opeir ing, as represented, and a concavo-convex and tapering catelnf, as shown, leading into the opening between its prongs, the whole being substantially as shown in the drawings.

Previous to applying the lower member to the edge of a box, such edge should be suitably recessed to admit of the proper fixation of the said member to it and the movements of the uppenmember, in order to engage it with or disengage it from the said lower member. The groove of the lower member guides the catch of the upper member into the slot, and thence into engagement with the catch of the lower member.

From the above it will be seen that in engaging the cover with the body of the box or casket such cover has to be moved endwise, it moving downward a little in the meantime; so in disengaging the cover from the body such cover has to be moved endwisein an opposite direction, it rising a little while being so moved.

I am aware that it is not new to have to the upper member of a burial-cover fastening an inclined or hooked catch, and to provide the lower member with a slotand one ortwo guidechannels leading and inclining to such slot, such being as shown in the said Patents Nos. 191,995 and 288, 189. Therefore I do not claim such,

' I am also aware of the collin-lid attachment shown in the United States Patent No. 350,155,

. whichalthough somewhat analogous todiffers in construction "cry materially from my improved attachment hereinbefore described, inasmuch as it has to itsmember to be fixed to the coffin-lidalongitudinal rib inclined on its lower edge and provided with locking-lugs to engage with a plate having an inclined groove and a T-shaped slot, whereas the partAof my attachment is simply a disk of metal havinga eoncavo'convex and tapering projection, as shown, and the part Bis of plate metal struck with a furcated opening, (I, the guide channel or groove 0, and the tapering tooth or catch f formed in it, as set forth. Therefore I make no claim to a coffin-lid attachment constructed as shown in the said Patent No. 350,155.

In the lower member of my coverfastening I not only have the slot and guide-channel, but a concavo-convex and tapering tooth or catch, which extends into the slot and serves, with the counter catch of the upper mcniber,to en- ICO gage the two members and to guidethem properly into engagement with each other. Be-

sides, each member is made of sheet metal and formed or struck by dies.

I claim- Theimproved box or casket cover fastening, substantially as described, consisting of the plate A, having the concavo-convexand tapering catch a, and the plate B, having the fur- 1 cated opening d, and the guidechannel or 10 groove 6, and the concavo-convex and tapering tooth 01' catch f,arranged with such opening as represented, all being essentially and for use as set forth.
